  2. Tree structure - Wikipedia

    en.wikipedia.org/wiki/Tree_structure

    A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the bottom.

    It is composed of water-conducting cells and associated cells which are often living, and is usually pale in colour. It transports water and minerals from the roots to the upper parts of the tree. The oldest, inner part of the sapwood is progressively converted into heartwood as new sapwood is formed at the cambium. The conductive cells of the ...

  5. Cladogram - Wikipedia

    en.wikipedia.org/wiki/Cladogram

    The incongruence length difference test (ILD) is a measurement of how the combination of different datasets (e.g. morphological and molecular, plastid and nuclear genes) contributes to a longer tree. It is measured by first calculating the total tree length of each partition and summing them.

  6. Clade - Wikipedia

    en.wikipedia.org/wiki/Clade

    In the diagram, lemurs and lorises are sister clades, while humans and tarsiers are not. A clade A is basal to a clade B if A branches off the lineage leading to B before the first branch leading only to members of B. In the adjacent diagram, the strepsirrhine/prosimian clade, is basal to the hominoids/ape clade. In this example, both ...

  7. Phylogenetic tree - Wikipedia

    en.wikipedia.org/wiki/Phylogenetic_tree

    The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).

  8. Bracket (tournament) - Wikipedia

    en.wikipedia.org/wiki/Bracket_(tournament)

    Different knockout tournament formats have different brackets; the simplest and most common is that of the single-elimination tournament. The name "bracket" is American English, derived from the resemblance of the links in the tree diagram to the bracket punctuation symbol ] or [ (called a "square bracket" in British English).

    The latter term is an affix found in other modern words such as cladodont (prehistoric sharks with branched teeth), cladode (flattened leaf-like branches), or cladogram (a branched diagram showing relations among organisms).
